git diff --staged for staged changes - Mini Project: Build & Apply

Using git diff --staged to View Staged Changes

📖 Scenario: You are working on a small project and have made some changes to your files. Before committing, you want to see exactly what changes you have staged for the next commit.

🎯 Goal: Learn how to use git diff --staged to view the changes that are currently staged in Git.

📋 What You'll Learn

Have a Git repository initialized

Have at least one file modified and staged

Use git diff --staged to view staged changes

💡 Why This Matters

🌍 Real World

Developers often want to review what changes they have prepared to commit. Using <code>git diff --staged</code> helps them see exactly what will be included in the next commit.

💼 Career

Understanding how to view staged changes is essential for software developers and DevOps engineers to ensure code quality and proper version control before sharing code with others.

1

Initialize a Git repository and create a file

Initialize a Git repository in the current folder by running git init. Then create a file named example.txt with the exact content Hello World.

Git

# Run git init and create example.txt with content 'Hello World'
# Your code here

Need a hint?

Use git init to start a new repository. Use echo "Hello World" > example.txt to create the file with content.

2

Stage and commit the initial file

Stage the file example.txt by running git add example.txt and commit it using git commit -m "Initial commit".

Git

git init

echo "Hello World" > example.txt
# Stage example.txt using git add and commit it
# Your code here

Need a hint?

Use git add example.txt to stage the file, then git commit -m "Initial commit" to commit it.

3

Modify the file and stage the changes

Change the content of example.txt to Hello Git and stage the changes again with git add example.txt.

Git

git init

echo "Hello World" > example.txt
git add example.txt
git commit -m "Initial commit"
# Change content of example.txt to 'Hello Git' and stage it
# Your code here

Need a hint?

Use echo "Hello Git" > example.txt to overwrite the file and then stage it again.

4

View the staged changes using git diff --staged

Run git diff --staged to display the changes that are currently staged for commit.

Git

git init

echo "Hello World" > example.txt
git add example.txt
git commit -m "Initial commit"
echo "Hello Git" > example.txt
git add example.txt
# Run git diff --staged to see staged changes
# Your code here

Need a hint?

The output should show the line removed -Hello World and the line added +Hello Git.
